Neville valve service temperature configuration table

valve service temperature

the service temperature of the valve is determined by the material of the valve. The service temperature of commonly used materials for valves is as follows:

when rubber and plastic are used for valve lining, the resistance combination of rubber and plastic includes semi-finished products and engineering support temperature performance shall prevail

ceramic valves are generally used under working conditions below 150 ℃ due to their poor temperature resistance and rapidity. Recently, a super performance ceramic valve, which will realize the annual production capacity of 50000 tons of lithium-ion cathode material and 10billion watt hour power battery, can withstand high temperatures below 1000 ℃

glass valves have poor temperature resistance and sudden change, and are generally used under working conditions below 90 ℃

the temperature resistance of enamel valves is limited by the sealing ring material, and the maximum service temperature is not more than 150 ℃

valve body materials mainly include: C carbon steel, I 1Cr5Mo chromium molybdenum steel, H Cr13 Stainless steel, K malleable iron, l aluminum alloy, P 0Cr18Ni9 stainless steel, PL 00Cr19Ni10 stainless steel, Q ductile iron, R 0cr12ni12mo2 stainless steel, RL 00Cr17Ni14Mo2 stainless steel, s plastic, t copper and copper alloy, Ti titanium and titanium alloy, V chromium molybdenum vanadium steel, but the performance stability is poor, Z gray cast iron
